Product style

  • Type A: The direct-connected centrifugal fan lacks accessories such as pulleys, bearing boxes, and belts. Moreover, the frame size of the centrifugal blower fan can be correspondingly reduced a lot, which is relatively convenient for transportation and installation. 
  •  
  • Type B: B-type transmission centrifugal fan: belt drive with pulley located in the middle of two supports, high requirements for bearings. 
  •  
  • Type C: The C-type industrial centrifugal fan is easy to maintain, and the speed can also be adjusted. The service life is relatively longer. The noise of the C-type fan is smaller, the price is relatively higher, but the operation is relatively stable.
  •  
  • Type D: Cantilever type, a transmission structure that uses a coupling to connect the centrifugal fan and the main shaft of the motor. The mechanical efficiency is higher than that of the C type transmission. It is suitable for medium-sized and larger industrial fans,induced draft fans and forced draft fans.
  •  
  • Type E: Double support, belt drive structure, two support bearings are installed on both sides of the casing, the impeller is in the middle of the two support bearings, and the pulley is installed on one side of the centrifugal fan. The optional range of fan speed is large, the flow rate is closer to the application needs, the motor installation position is more flexible, and the pulley is more convenient to remove. Compared with the C-type transmission, the radial load of the bearing is small, and the industrial fan runs relatively smoothly. Suitable for centrifugal fans with double suction or large single suction and with a wide range of performance changes.
  •  
  • Type F: F-type centrifugal fan is driven by coupling, double support, the impeller is installed between two bearings, there are single suction double support and double suction double support fan, which is characterized by high transmission efficiency, low noise and no vibration. F-type centrifugal fans are more suitable for large air volume and high wind pressure. Compared with the cantilever support structure, the double-support structure is more stable and has less vibration.

Advantages:

  •  1.CNC automatic robot welding equipment:
  • The industrial fan adopts robotic arm welding technology,the weld seam is uniform and spatter-free, in line with EU standards. 
  •  
  •  2.Shot blasting machine sand blasting:
  • Derusting the centrifugal fan casing, so that the surface of the fan casing is clean, showing the original luster of the metal, increasing the roughness of the surface of the workpiece, which is conducive to the subsequent spraying adhesion.
  •  
  • 3.All copper motor - new:
  • All centrifugal blower fan can be equipped with ABB/Siemens/WEG, etc.according to customer request. Have established a long-term strategic partnership with those brand. 
  •  
  • 4.Can be produced to API 673 standards:
  • Cover the minimum requirements for centrifugal fans for use in petroleum, chemical, and gas industry services. 
  •  
  • 5.Can use NSK/SKF etc., and has established a long-term strategic partnership with them:
  • All the industrial fans,FD fan/ID fan can be equipped with NSK/SKF bearings. 
  •  
  • 6.2D and 3D drawings can be designed and provided for free:
  • Provided drawings for all kinds of the industrial centrifugal fans. 
  •  
  • 7.High temperature fan with cooling shaft plate, which can quickly dissipate heat:
  • When the medium temperature of the induced draft fan is high,this will work. 
  •  
  • 8.Noise level < 80 dB
  •  
  • 9.Brute force test available:
  • All the centrifugal fans can be brute force tested, the case is hard to withstand.

Application:

  • Boiler fans can choose centrifugal or axial flow according to the specifications of the boiler. According to its function, it is divided into boiler fan, which conveys air to the boiler; boiler induced draft fan draws away the flue gas in the boiler.
  •  
  • Fan for ventilation This type of fan is generally used for ventilation and heating and ventilation in factories and various buildings. The pressure is not high, but the noise requirement is low. Centrifugal fans or axial fans can be used.
  •  
  • Fans for industrial furnaces (iron furnaces, forge furnaces, metallurgical furnaces, etc.) This kind of fans requires a high pressure, generally 2940 ~ 14700N/m2, that is, the range of high-pressure centrifugal fans. Due to the high pressure and the large peripheral speed of the impeller, the impeller must be designed with sufficient strength.
  •  
  • Centrifugal fans are mostly used to transport pulverized coal in the combustion system of thermal power station boilers. The pulverized coal fan can be divided into two types according to different uses: one is the silo type pulverized coal fan, which blows the pulverized coal in the silo from the side into the furnace. The pressure is high; the other is the direct-blown pulverized coal fan, which directly sends the pulverized coal to the furnace. Due to the serious wear of the impeller and the casing of the pulverized coal, wear-resistant materials should be used.
  •  
  • Mine fan It has two types: one is the main fan (also known as the main fan), which is used to deliver fresh air to the well. Also known as local fan), it is used for ventilation of mine working face, its flow and pressure are small, and explosion-proof axial fans are mostly used.

FAQ
Q: we have no data about the air quantity of the fan, can you give us some recommendations?
A: Yes, just let us know the tunnel diameter/length, and our engineer will design it for you.
Q: we want ventilation fans for our coal mine, is there anything we should pay attention to?
A: if using fans in a coal mine (especially underground), an explosion-proof motor and aluminum alloy impeller is necessary.
Q: We talked to you about cooling bearings (oil) with air, can you suggest a solution?
A: Yes, we have done a similar project before. When the smoke pump is running, the friction between the bearings will generate heat, and we will add antifreeze, so it will not freeze. When the smoke pump is not running, it must be the liquid in the bearing box is completely cleaned to prevent freezing when stationary. As long as the above operations are ensured, there will be no problem with the smoke pump.
